The most common clinical complications associated with
metal-ceramic and all-metal restorations are identified along with methods of
minimizing or preventing them. Methods of managing the complications are
described when they do occur.

Learning Objectives:

Identify the most common complications associated with single crowns

Identify the most common complications associated with fixed partial
dentures

Develop strategies that can be used to minimize or eliminate loss of
retention

Describe methods that can be used to increase resistance form when
deficiencies are present

Identify the benefit of circumferential irregularities

Describe where circumferential irregularities are best located

Abstract:

Knowledge of the factors that cause complications and failure in fixed
prosthodontics enhances our ability to develop effective treatment plans,
facilitates success, promotes optimal doctor-patient communication regarding
anticipated treatment outcomes and provides early diagnosis of problems
encountered during long-term maintenance. This presentation will identify the
most common complications encountered with conventional single crowns and
conventional fixed partial dentures and describe methods of minimizing or
preventing their occurrence as well as managing the complications when they
occur.
